1. For your safety

The machine meets the requirements of safety standard ANSI

B11.3.

This chapter describes the safety concept. The chapter

describes how potential dangers can be avoided. The overview

of residual risks contains measures to be taken by the operator

in order to reduce the residual risks.

Notes

■The operator must adhere to the valid safety and accident

prevention regulations of the respective country and the

safety laws of the state and of the region!

■USA and Canada: TRUMPF also recommends that the

safety regulations for ANSI press brakes be observed.

Certain operations can be a source of danger during operation.

The documentation contains warnings before the instructions for

these activities. There are warning plates on the machine.

A warning contains signaling words that have been explained in

the following table:

Signaling word Description

DANGER ... refers to great dangers. If not avoided, it can result

in death and serious injuries.

WARNING Refers to a dangerous situation. It could lead to seri-

ous injuries, if it is not avoided.

CAUTION ... indicates a potentially dangerous situation. It could

lead to injuries, if it is not avoided.

NOTICE If such a situation is not observed, it can lead to dam-

age to property.

Signaling words Tab. 1-1

Example of a warning:

Risk of fatal injury due to falling load!

ØObserve safety regulations for the handling of heavy loads.

ØNever walk under a suspended load.

ØUse certified tackle and means of transportation of sufficient

size.

ØEmploy qualified technicians to transport the machine.

ØCarry out transport in accordance with the transport regula-

tions.

Warnings and warning signs

DANGER

2. Operational safety

The machine can result in the following dangers if it is used

inappropriately or for purposes other than those intended, or

else if it is not safe to operate:

■Dangers to the safety of the operator.

■Damage to the machine and to other property of the opera-

tor.

■Negative effect on the effective functioning of the machine.

2.1 Intended use

The user may use the machine only in the industrial sector.

Installation, operating and transport conditions defined by

TRUMPF must be adhered to and maintenance work must be

carried out in accordance with the Operator's manual. The user

must observe the specifications of the country in which the

machine is being operated as well as national and regional

safety and accident prevention regulations.

The user may bend cold sheets using the machine.

The following is not permitted:

■Unauthorized alteration or conversion of the machine by the

user or personnel.

■Any working procedure that impairs the safety.

■Processing of hot, splintering or brittle materials.

■Use of tools from other manufacturers without release by

TRUMPF.

■The storage of tools no longer required on the press beam.

Any use going beyond this is considered to be unauthorized

use. TRUMPF is not liable for any damage, especially personnel

injuries and production failures resulting from this. The risk is

borne solely by the operator. The warranty will be voided.
